remarks:        This range was initially allocated by InterNIC prior to the
remarks:        formation of Regional Internet Registries (RIRs). The early

remarks:        to be administered by each RIR based on the region in which
remarks:        the majority of resource holders resided.
remarks:
remarks:        This early registration block has been transferred to APNIC's
remarks:        administration. However, not all of the resources under this
remarks:        block have been transferred to APNIC.
